Im getting double shadows on my hdri, please help. see attached.

Whats up folks, I was hoping someone could shed some light on something for me. Im using and hdri image and a light dome. But im getting double shadows and I cannot figure out why.

 

 

In the attached image I have a kitchen, there is sun light coming through the window, (the son is directly aligned with the sun of the hdri) and im getting shadows in that direction, but im also getting a second set of shadows that don't correspond to the direction of the sunlight.

 

 

I only have the domelight with the hdri and my sun light lighting the scene,.. I was hoping someone could help me make sense of this. I double checked to make sure I don't have any more lights in the scene, I also double checked to make sure that my sun was still aligned with my hdri. For the life of me I cant figure out where that other shadow is coming from.

Ok so I figured out the problem I just need to know how to fix it. So it it turns out that, in the "vrayHDRI" when I assign a map and choose " spherical" as a mapping type, it offsets my HDRI about 97 degrees. is this a glitch has anyone had any issues with this?

 

 

In addition to offsetting the HDRI in the viewport, it also offsets it in the render so that if I swing the camera around in the viewport to see the sun, and then render, the render is a totally different view,.. the render has the hdri oriented to a different degree.

 

 

now that would not be an issue if I could wire parameter the sun to the 3ds max standed mapping type, and just link the z rotation to the u offset of the standard mapping type but theres no option for that in the when I try to set up the wireparamenters, only a textures section that is the " spherical mapping" type

Try this

 

paramWire.connect vr_sunCtrl.rotation.controller[#Z_Rotation] vr_HDRI[#horizontalRotation] "-Z_Rotation"

 

vr_sunCtrl is a Circle(Spline)

 

vr_HDRI is the Vray_HDRI Map applied under the domeLight.

ok so for anyone having a similar issue, this is how you fix it

 

 

put vrayhdri in mat slot, then instance into the environment, after that instance ( from the environment) to your domelight, then when you wire parameter make it so that the vrayhdri spinner controls the rotaion of the domelight ( not the other way around as I was told on numerous tutorials) after that link your sun and its target to your dome. that's it .

I forgot to mention, you have to uncheck " lock to dome orientation, that seemed to be the major player in the issue.
